What are the self ignition temperatures of crude oil?

The self-ignition temperature of crude oil typically ranges between 200 to 300 degrees Celsius (392 to 572 degrees Fahrenheit). However, this temperature can vary depending on the specific composition of the crude oil, including its viscosity and the presence of lighter fractions. It's important to note that self-ignition can occur in the presence of an ignition source, such as heat or sparks, particularly in confined spaces. Proper handling and storage are essential to mitigate fire risks associated with crude oil.
